UNIX Telnet Security
Because QXI communicates over telnet via HTTP, the account log-in ID and password are sent using unencrypted text. Since this may compromise system security, you should configure the telnet environment with server-side security measures in mind.
A range of security options exists to solve the unencrypted log-in and password problem. This section outlines two sample security setups: one providing a maximum level of security and one providing less security but more flexibility for Progress client session and home directory access. In both setups, it is recommended that you use a restricted shell (rsh).
